I think you have a problem with CR Encoder. And need to replace it. Or clean or replace T-Fence.
As we can see on picture, the problem is UniDir adjustment. But in this printer you can set adjustment values for whole printhed.
Colour on printheads: KY CM MC YK.
You can see: KY - no space between colors. CM - with space.
It impossible to adjust space between colors inside one printhead.
